For a carbon atom that is sp2 hybridized, I understand that the electron configuration would be Yes, 1s2 2s1 2p3 which is a 2s up arrow,and 3 orbtials that are 2p up arrows but then since the four bonds hybridize to form four sp3 hybrid bonds how do I write this? Also for an ...

So the C in methane would be sp3 correct? So does this mean that the electron config would be 1s orbital with an up and down arrow, 2 sp2 orbitals with 3 single up arrows, and a 2p orbital with a single up arrow?

I am having trouble figuring out the electron configuration for a carbon atom when it is in a molecule such as methane. I know that the ground state configuration for carbon is 1s2 2s2 2p2 but im not sure how to figure it out when it is bonded to other atoms. Thank you for the...
